Abstract

L'invention concerne des codeurs, des décodeurs, des procédés de codage et des procédés de décodage de données de signaux vidéo pour un bloc d'image. Un codeur de codage des données d'un signal vidéo pour un bloc d'image comprend un sous-échantillonneur à mode de rafraîchissement à résolution réduite (RRU) (515) qui permet de sous-échantillonner un résidu de prédiction pleine résolution au moyen des données provenant d'au moins un bloc d'image voisin, et de former, par conséquent, un résidu de prédiction sous-échantillonné à faible résolution pour le bloc d'image.
